supporting 22 is a sprocket wheel 25 over which parses an endless driving chain 82- from any suitable source of power 81. Rotatably mounted in suitable bearings in the side` members 13 and arranged parallel to, but spaced apart from, each other a suitable distance are shafts 26 to each of which is secured, in tcrmediate the ends thereof, a downwardly dependin lever 27, the `lower ends of these levers 27 eing pivotally attached to a horizontally arranged operating bar 28 which extends on the right hand end,` as viewed iii F ig. 2, to an operating mechanism (not shown) and to the left hand end is secured one end of a. coil spring 29, the other end of this spring 29 being secured to a cross niembei' extending between the upiights 11. Secured to each of the shafts 26 near each end thereof` and extending outward therefrom in a. substantially horizontal direction are arms 30, the outer or free ends of which are pivotally connected to shafts 31 having their ends secured to the side members 352 of a rectangular frame, the side members 32 being tied together at their ends by end members 33. Movement of theoperating bar 28 to the right will cause the rectangular frame to be moveddownwardly, while yet being maintained horizontal, while a` reverse movement, or movement to the left of such operating rod` 28, under thcinfluence of the spring 29, will `cause an upward movement of said frame while yet maintaining such frame substantially horizontal, as shown in Fig. 2. `Secured to the side members 32 of the rectangular frame and extending downwardly therefrom, and on` each side thereof, are spaced hangers 34 provided with bearings 35 at theii` lower end,`and in each pairof oppositely arranged hangers 34 is rotatably mounted a. shaft 36, each ot'" which has secured `thereto a bell crank lever comprised of a substantiallyY horizontally arranged arm 37 and a substantially vertically arranged arm 38, the outer end of the horizontal arm 37 being provided with a weight 39, while to the upper'end of each of the vertically arranged ariiis 38, with theexception of the extreme left hand arm 38, as viewed in Figs. 1 and 2,' is secured one end of a chain 40, the other end of such chain being secured to the next vertical arm' 38, to the left, as viewed in Figs. land Q, and at a point intermediate the ends thereof. To the upper or free end of the extreme left hand vertically arranged arm 38 is secured one end of a chain 4l. the other end of which issecured `to the free end of a switch arin`42 ofl a control switch 43itliat is secured on a bracket 44 on one of the uprights 11, as clearly shown in Fig. 1. The switch 43 is connected in the control circuit of a motor 81 by cable 80. Secured to each of the shafts 36 near the ends thereof are members 45 which members extend substantially upwardly from said shafts 36, and

the upper ends of all of said members 45, with the exception of the extreme right hand pairof suoli members, has secured thereto, or formed integral therewith, extensions or stops 46 which, when the rectangular frame comprised of the members 32 and 33 is in its upward position as shown in Fig. 2, brings the upper end of the stops46 into a position adjacent to, but slightly below, the plane in' which lies the top of the top reach ol' the endless conveyer chains 16 and the bottoni surface of the pallets 47, each of the pallets 47 containing t ie plurality of brick 48. The extreme right hand end pair of members 45 on the right hand shaft 36 `have secured to the top,` or formed integral therewith, upwardly extending members 49, the upper end of such members 49 being drilled at 5() to re ceive for sliding movement therein pins 51, the upper end of the members 49 being slotted at 52 to receive a pin 53 extending transversely of the pins 51 and thereby limit both the inward and outward movement ol' the pins 51. Between the inner or lower end of the pins 5l and the bottom of the drilled portion 50 is placed a compressing spring 54 which tends to maintain each ot' the pins 51 in its upward iosition. The distance from the center ot' t e shaft 36 to the upper end of the pins 51 is reatcr than the distance from the center of tie shafts to the upper ends of the stops 46 so that, when ,i

the rectangular frame comprised of the members 32 and 33 is in its upward position, as shown 1n Fig. 2, the pins 51 will lie above the plane passin through the top of the top reach of the en ess conveyer chains 16 and in position to be en agedby the oncoming stream of loaded pal ets 47. Secured to thc extreme right hand end of `the frame meinbers 32 are stops 55, the upper ends ot' which lie in substantially the lsaune.horizontal plane as lie the upper ends oi' the ins 51.`

Secured to the side mein iers 13, spaced apart from, and parallel to each other, are shafts 56 ando?, and rotatably mounted on the shaft 57 is a substantially U shaped frame 58 to the ends of the portion joining the legs thereof is secured upwardly extending stop fin ers 59, and rotatably mounted at the en s of the arms of the U shaped member 58 is a shaft y60. Secured to each end of the shaft 60 are levers 61 which are each provided with elongated slots 62 at a point intermediate their` ends and through which slots extends the shaft 56, while rotatably mounted at the ends of each of the levers 6L is a roller 63, this last described mechanism operating as a combined stop, alining, and releasinv device for the oncoining stream of loaded palletsy 47 as they are fed onto the storage conveyer from the diying apparatus.

Assuming that the apparatus is constructed as above described and that loaded pallets bringing the stops 46 into operative position l with relation to the pallets ing the stop pins 51 andstops 55 into such de ress, such ro`llers'63 :about the 'pivotal po1nt'627ofthelevers 61 simultaneously depressingthe stop fingers 59 which, however, immediately return l to their normal or, upward osition','as shown in Fig; 2, when t e londe *pallet has passed beyond-the roller 63. Simultaneously "with the f return of the stop fingers 59-to normal'position, the lrollers 63 also return to a normal position, and the loaded palletl r47-A `will be 'brought to rest against the stop fingers 59. Should the loaded pallet 47 have been delivered to the conveyer Ychains 16 with one end further advanced than the other, the engagement of thev loaded pallet by the stop fingers will correct such disalinement and the loaded pallet, when' released, will be given va fair start' over the conveyer chains 16. The next succeedingpallet 47 ,with `its load of bricks 48, will,-in like manner, depress the rollers'63 simultaneously depressing the stop tingers59 which thereupon release the first of'said pallets 47 and said pallet will therefore, be moved to the right by the conveyer chains 16, `this movement being continued indefinitely. It is assumed that'the operatin rod 28 has been moved to the right against t e tension'of the spring 29. and that, thereforethe rectangular frame comprised of the members 32 and 33 is, in its downward position, thereby maintaining all of the stop fingers 46, the stop fingers 51, and the stop members out oit possible engagement with the oncomin stream of palletsV 47 so that, under norma conditions of the device with which the present invention is adapted to function, theconveyer chains 16 act merely as conve-ying chains.

Should, for any reason, the m'echarnism-l with which thepresent invention is adapt' ed to function, be deranged or if, for any reason, such mechanism is unable to properl take-care of any more loaded pallets 47, tlie operating rod 28 is released, whereupon the spring 29 moves such operating rod 28 to the left, thereby causing an upward movement of the horizontal rectangular frame comprised of the members '32 and33 and 4 and also bringa position as to engage the pallets 47. The pins 51 are, in reality, safety stop pins and are constructed as above described so that, if,

,at the time 'the rectangular frame is moved upwardly by the spring 29, a pallet 47 should be above the upper ends of the pins 51, such pins will move downwardly under the weight tion ofthe palletiandi load `a ainst'thetension of the pring .f 54 and sai pallet will Avbe moved orwardly by the conveyer chains 16 and willbe brought positively to rest by en.- gagingwith the stops `,55. -The nextsu'cceedmg.. pallet .47 will be'brought to rest in the position .shown in Fig. 2 by the pins 451.`

Normallythe' stop pins 46in the downwardposition kofthe rectangular frame will be in the osition shown-jinfdot and dashlines 1n 1g. 5, and when the rectangular lframe has been moved to its' u permost position, the stops 46. willbe in t e position shown in dotted `linesfin Fig. 5. In the 'uppermost' position of the sto fingers 51 which willcorrespond with-the .n otted position of the stop fingers 46, as shown in Fig. 5,' the upper ends will be in position to engage with the oncoming pallet 47 and such allet, in its onward `1novement,'willvswing t e ins` 51 from Athe inclined position shown in Y ig. V5 to a vertical position, as shown in 'Fig.,2., The chain 4() attached tof the upper end of the arm 38 of the extreme right hand bell crank lever,

comprised'of the arms `37 'and38 is so proportioned that movement from kthe inclined Aposition shownin Fi 5 to the vertical position will-.move the rst or right hand pair vof stops 46 from the inclined position shown in-Fi 5.-to'the Vintermediate inclined posiesignated by the numeral 57 `in Fig.

5 and in position to be engaged by the next l succeeding loaded pallet 47 which, being carried to the right byl conveyer chains 16, will move the first pair of stops 46 into the upright position, l as shown in Fig.'5, the

ychain 40 connected to the bell crank lever as-, 4 sociated with such first pair of stops 46 moving the next pair of stops 46 to the position indicated by 57 in Fig. 5this sequence of operatlons being continued until the last stop iinger isinoved to the intermediate position.

As such last pair of stops 46 moves to the upright positlon, as shown inl Fi 5, the..

38 pulls the switch blades 42 out of engagechain 41 attached to the free end o thearm ment with the cooperating contacts thereof on the switch 43 breaking, in thismanner, the power circuit leadingto they motor 81 f that operates the device for feeding the loadets 47 onto the conveyer chains 46., The distance between the pallets as they'are ed pa fed onto the conveyer chains 16 is approximately two feet so that the next succeeding pallet after the oneen aging the extreme left hand pair of stop n ers 46 Awill come into engagement with, `and e stopped by, the

fingers 59 and the next succeeding pallet after the one now in engagement with theffingers 59 will be retainedon the lfeeding mechanism operatedby the motor controlled by present invention to be stillout of action, the

the switch'43 so that, auming the mechav nism at the right'of theVv mechanism of the present invention will beheld in the position shown in Figs. l and 2. When the mechai' nisni to the riglht of that shown in Figs. 1

a' the position shown by the stop fingers.

lVhile 'l have necessarily described my present invention as being adapted particularly 4for moving and storing up, in case of need, a. plurality of allets loaded with `brich, and referred to a ove, it is obvious that I may em loy my device for handling articles other tlianploaded pallets and I do not wish to limit myself to the transportation of this particular article other than as pointed out in the appended claims.

Having thus described my invention, what I I claim as new is:

combination o 1. In an improved storage conveyer, the

a pair of conveyer chains runninol parallel to, and spaced apart from, each other, alining and release means assodriving said conveyor chain continuously inl one direction, means for alining articles to be transported located at the entrance end of said conve er, releasing means associated with said a ining means and operating to release a plurality of articles to be transportsaid ed in succession, means for stoppin articles in succession, and means opera le on the filling of the storage conveyer for preventing further feeding of articles thereto.

3. In an improved storage conveyer, the combination o an endless conveyer chain, means for driving the same, means associated with the conveyer for stopping a plurality of articles to be conveyed in succession and holding the same immovable while allowing the conve er to be kept in motion, and means opera le, when the conveyer is loaded to capacity, for stopping further movement thereof.

In testimony whereof, I have signed my name to this specification. i i
